- Until now, mainly autologous plasma was used to produce fibrin sealant with the CS-1. Within Sanquin there is a question whether fibrin sealant can be produced from the allogeneic quarantaine plasma that is in stock. Therefore in this study will be studied whether allogenous single donor fibrin sealant produced using the CS-1 is effective in wound healing and as consequence of this can be registered as a product of Sanquin.
